ABSTRACT
We propose a new equation to describe the relation between otolith length (OL) and somatic length (fork length [FL]) of fish for the entire lifespan of the fish. The equation was developed by applying a mathematical smoothing method based on an allometric equation with a constant term for walleye pollock (Theragra chalcogramma) --a species that shows an extended longevity (>20 years). The most appropriate equation for defining the relation between OL and FL was a four-phase allometric smoothing function with three inf lection points. The inflection points correspond to the timing of settlement of walleye pollock, changes in sexual maturity, and direction of otolith growth. Allometric smoothing functions describing the relation between short otolith radius and FL, long otolith radius and FL, and FL and body weight were also developed. The proposed allometric smoothing functions cover the entire lifespan of walleye pollock. We term these equations "allometric smoothing functions for otolith and somatic growth over the lifespan of walleye pollock."

    We quantified the growing season of yearling walleye pollock ( Theragra chalcogramma) and related it to annual cycles of water temperature and day length. The study was restricted to members of the 2000 year class and thereby controlled for inter-annual variability. Juveniles were sampled from...
